METAL ROOFING.

SEPECIFICATION forming part of Letters Patent. No. 334,624, dated January 19. 1886.

Application filed October 28, 1885. Serial No. 181.198. (No model.)

This invention relates to metal shingles provided with felt lining for roofing purposes; and it consists of sheet-metal plates having combined therewith sheets of roofing-felt,

forming shingles, which are constructed and applied to the roof, as hereinafter fully de: scribed, and pointed ontin the claims.

In the accompanying drawings, Figure 1 is a view showing some of my improved felt-lined metal shingles as seen when laid upon a roof. Fig. 2 is a sectional view showing the method of laying these shingles,and interlocking their felt linings. Fig. 3 is a sectional view showing the interlapping of the upper edges of the felt lining with the central lock of the over lying sheets. Fig. 4 is an under-side view of oneof the shingles, showing the method of at taching the felt lining thereto.

A is a sheet of metal of suitable size and form, and Bis a sheetof roofing felt or paper, the size of which is somewhat greater than the metal sheet. The two side edges and thelower edge of the metal sheet are folded over, and in said folds are embraced the edges of the sheet of felt, thus securing the felt lining to the metal. The left-side fold of the metal sheet has a return-fold, a, which projects a short distance beyond the edge of the sheet. The right-side fold of the felt, also, has a returnfold, b, which projects considerably beyond the edge of the metal. The upper edge of the felt also projects considerably beyond the upper edge of the metal. Across the central part of the felt lining is cut a slot to form a flap, G, and the side projecting piece of the lining has a slit, (1, out in line with said flap O.

The method or plan of laying these metal and felt lined shingles is as follows: First, a double row of them is laid along the edge or caves of a root, in like manner to ordinary wooden or slate shingles, with the projecting edge of the metal a underlying the edge of the adjoining sheet and overlying the projecting edge of the felt sheet, as seen by dotted lines in Fig. 1. These sheets are secured to the roof by nails driven through their upper part, in like manner to slate or other shingles. The second and all succeeding rows are laid, as shown in Fig. l, breaking joints like slate or other shingles. In thus laying them the top projecting edges b ofthe felt linings are turned down over onto the metal, and the flaps O are slid up in under said folds, as seen at E, Figs. 2 and 3, thereby interlocking the felt lining together, thus laying the shingles in even regular rows, with the linings closely interlocked, making tight compactjoints.

Having described my invention, I claim lJThe metal-rooting shingle A, provided with a'felt lining, B, having side and end projeclions and central cross -cnt flap, 0, substantially as described.

2. In metal roofing, the combination of the metal shingles A, provided with felt linings B, having side and end projections and central cross-cut flap, C, said shingles being laid in rows, with their side edges lapping and their upper edges interlocked with the central flap, substantially as described.
